There is no description on the character creation page of RuneScape?

I just started playing on RuneScape, well, actually, I haven't started playing yet. I'm on the character creation screen and there are different kinds of clothes designs, some with weapons, some without. I don't know what each of them specifically do. Why are there no descriptions as to what that certain class is?

Here's a screenshot of one without weapon.

And here's a screenshot of the other one with a weapon.
